Population concentration in Indian urban cities demands for the fast transport systems. As a viable solution, development of effective intercity transportation system has become the need of the hour. Railway transportation possesses all the qualities needed in modern intercity transit systems because of its travel speeds, timely service and efficiency. Out of the many railway systems available across the world, the linear motor powered railway systems are gaining popularity due to the inherent advantages of linear motors over rotary motors used in these systems. Linear induction motors and linear synchronous motors are widely used in the propulsion systems of these transports. However, because of the simple construction with lower manufacturing and maintenance cost, linear switched reluctance motors (LSRMs) are widely researched for use in such applications. Nevertheless, nonlinearity of this motor alters its force performance. This paper therefore presents a modified structure of LSRM designed to overcome these challenges posed by conventional LSRM for use in recently developed Mumbai monorail train system. Rail car specifications used in actual Mumbai monorail system are considered for development of the linear propulsion system. The modified LSRM is designed to meet these specifications and analysed using finite element method.
